I . How Leaves neuter ColorII . IntroductionIn countries that experience capitulation , some channelizes transform the coloring of their leaves from green to a variety of autumn emasculate red , yellow orange , br experience , and the colors in between . Though science have yet to in full understand how and wherefore trees do this , we do hunch over that ever- changing color has something to do about the trees survivalIII . ProcedureThe World colossal wind vane was used in the collection of info regarding the process of leaves changing color . Information gathered were then(prenominal) read and canvas . These data were then put into own words by the researcher in the Results sectionIV . Results Chlorophyll is the centerfield that makes the leaves green . Chlorophylls argon used in the food do process of a plant or a tree . Without it the plants would starve to oddment . In summer , chlorophyll is copious in the leaves , that s why they maintain that green colorWhen autumn draws nigh(a) , the trees sense that the long time ar getting shorter and that the temper is getting colder . This triggers the trees to gradually put down chlorophyll swap . Due to chlorophyll s decreased front in the leaves , new(prenominal) pigments that were in the leaves all along just were dominated by the green chlorophyll , starts to show up . This pigment is called carotenoids , they enrolment yellow , brown , and orange discrepancy of colors on the leaves . Anthocyanins on the other hand give the leaves its red hues . Anthocyanins , only , are not present in the leaves at the same time as chlorophyll and carotenoids . Their exertion is based on phosphate levels and bright decreaseing . phosphate levels are usually laid-back in the leaves but on autumn in discharge , levels drop and triggers the production of Anthocyanins , the brighter th! e light during this time , the more pictorial the colors becomeV . DiscussionLeaves of certain plants and trees intensify color because chlorophyll production stops .

Production stops as preparation for pass , when sunlight and water are scarce , vital components in food production . This closedown down of the plant or tree causes a range of a function response that leads to the leaves loosing its green pigment (chlorophyll ) and eventually the leaves are disposed . at that place s no point in keeping them if they take on t have purpose , at least just for the nail down and autumnVI .
